[0032] The pressing fixture of the first aspect embodiment and the pressing mechanism of the second aspect embodiment of the present invention will be described below with reference to the accompanying drawings. It should be noted that, for ease of understanding and description, in the embodiments of the present invention, the up-down direction is indicated as the first direction, and the front-back direction is indicated as the second direction. The second direction is the direction of conveying the base film and the padding adhesive, and the first direction is perpendicular to the second direction.

[0033] The first aspect of this utility model provides a pressing jig 100 for pressing a base film and a padding adhesive, see reference. Figures 1 to 3As shown, the pressing fixture 100 includes a first conveying cavity 111 and a second conveying cavity 121, wherein the first conveying cavity 111 and the second conveying cavity 121 are formed inside the pressing fixture 100, and the second conveying cavity 121 is disposed above the first conveying cavity 111 in a vertical direction. The first conveying cavity 111 is used to conduct the base film, and the second conveying cavity 121 is used to conduct the shim adhesive. Since the area of ​​the base film is larger than the area of ​​the shim adhesive during the pressing operation, placing the second conveying cavity 121 above the first conveying cavity 111 allows the part of the base film not bonded to the shim adhesive to adhere to the inner wall of the first conveying cavity 111 under the action of gravity, thereby obtaining support and preventing the part of the base film not bonded to the shim adhesive from forming creases under the action of pressing force during the bonding process. The first conveying cavity 111 and the second conveying cavity 121 are connected to the two ends of the pressing fixture 100 in a front-back direction, forming an inlet 130 and an outlet 140. Since the first conveying chamber 111 is connected to the second conveying chamber 121, the inlet 130 and outlet 140 of the first conveying chamber 111 are also connected to the inlet 130 and outlet 140 of the second conveying chamber 121, allowing the base film and the shim adhesive to be input and output together into the pressing fixture 100 for pressing. The height of the outlet 140 in the vertical direction, i.e., the distance between the upper and lower walls of the outlet 140, is less than the sum of the thicknesses of the base film and the shim adhesive in the vertical direction. Since the shim adhesive is an elastic material, when the base film and the shim adhesive are output through the outlet 140, the outlet 140 will squeeze the base film and the shim adhesive, causing the shim adhesive to deform, thereby achieving the initial pressing of the base film and the shim adhesive.

[0034] Specifically, when pressing the base film and the shim adhesive together, the position where the base film needs to be bonded to the shim adhesive is located at the connection between the first conveying chamber 111 and the second conveying chamber 121. The base film and the shim adhesive enter the first conveying chamber 111 and the second conveying chamber 121 respectively through the discharge port 140. This allows the shim adhesive and the base film to come into contact with each other for precise bonding during the conveying process inside the pressing fixture 100. When the shim adhesive and the base film are conveyed to the discharge port 140, the discharge port 140 applies extrusion pressure to the shim adhesive, allowing the shim adhesive to be pressed onto the base film, achieving precise bonding between the base film and the shim adhesive.

[0035] The pressing fixture 100 of this embodiment defines a first conveying cavity 111 for conveying the base film and a second conveying cavity 121 for conveying the shimming adhesive. The first and second conveying cavities 111 and 121 are connected, allowing the base film and shimming adhesive to contact and adhere to each other when placed in the first and second conveying cavities 111 and 121 respectively. Simultaneously, the contact positions of the base film and shimming adhesive are defined by the first and second conveying cavities 111 and 121, ensuring precise fit between them. Then, the height of the outlet 140 is less than the sum of the thicknesses of the base film and shimming adhesive, so that the base film and shimming adhesive are subjected to downward pressure when output from the outlet 140, thereby achieving precise pressing.

[0036] In some embodiments, see Figure 4 As shown, a pressing portion 122 is formed extending downwards from the side of the second conveying chamber 121 facing the first conveying chamber 111. One end of the pressing portion 122 extends to the outlet 140 in the front-back direction. The pressing portion 122 is used to abut against the shim adhesive to press the base film and the shim adhesive together. Specifically, one end of the pressing portion 122 extends to the outlet 140, so that the height of the outlet 140 in the vertical direction is different from that of the inlet 130 and is less than the sum of the thicknesses of the base film and the shim adhesive. This allows the base film and the shim adhesive to be pressed against the wall of the outlet 140 when they are output from the outlet 140, thus achieving initial pressing. In this embodiment, after the shim adhesive enters the second conveying chamber 121 and is conveyed a certain distance, the shim adhesive will come into contact with the pressing portion 122. The pressing portion 122 will apply pressure downwards to the shim adhesive, thereby promoting the bonding between the shim adhesive and the base film. Furthermore, the pressing part 122 is arranged in the front-to-back direction, so that when the shim-raising adhesive passes through the pressing part 122, each part of the pressing part 122 will provide uniform downward pressure to the shim-raising adhesive, thereby making full contact between the shim-raising adhesive and the base film, improving the bonding degree between the two, thereby avoiding insufficient contact pressure provided by the inner wall of the second conveying cavity 121 to the shim-raising adhesive and the base film, resulting in insufficient pressing of the shim-raising adhesive and the base film.

[0037] Furthermore, in some embodiments, see [reference] Figure 4As shown, the pressing part 122 and the first conveying cavity 111 are spaced apart by a vertical distance H1, which gradually decreases in the front-back direction. Specifically, the wall surface of the pressing part 122 facing the first conveying cavity 111 is spaced apart from the bottom wall of the second conveying cavity 121 (the wall surface of the second conveying cavity 121 facing the second conveying cavity 121 in the vertical direction), with a distance H1 between them. The gradual decrease in the distance H1 in the front-back direction causes the extrusion pressure applied by the pressing part 122 to the shim and the base film to gradually increase. The gradual increase in extrusion pressure achieved by the gradual change in the distance H1 causes the shim to gradually undergo compression deformation during conveying, thereby preventing the shim from being subjected to large sudden pressure changes when it comes into contact with the pressing part 122, avoiding stress concentration and stress changes in the shim, and reducing the breakage rate of the shim.

[0038] In some embodiments, see Figures 3 to 5 As shown, the two ends of the pressing part 122 extend to the inlet 130 and the outlet 140 respectively in the front-rear direction. The inner walls of the end of the pressing part 122 at the inlet 130 and the end of the second conveying cavity 121 are rounded. Specifically, the end of the pressing part 122 is provided with an arc structure 150, which is located at the outlet 140 and connected to the inner wall of the second conveying cavity 121 on the side facing the first conveying cavity 111. During the conveying process, the pressing part 122 compresses the padding adhesive to gradually bond the padding adhesive and the base film. Extending one end of the pressing part 122 to the outlet 140 can prolong the compression time of the pressing part 122 on the padding adhesive, thereby improving the bonding efficiency of the base film and the padding adhesive. Furthermore, since the pressing part 122 is used to abut the padding adhesive, the gap distance H1 between the pressing part 122 and the first conveying cavity 111 will be less than the thickness of the base film and the padding adhesive in the vertical direction. When the shim and the pressing part 122 first come into contact, the shim needs to deform before entering the second conveying chamber 121. The pressing part 122, with its arc-shaped end at the outlet 140, improves the fit between the shim and the pressing part 122, thereby increasing the smoothness of the shim entering the second conveying chamber 121. Simultaneously, the arc-shaped structure 150 prevents the shim from being scratched by the edges of the pressing part 122 when entering the second conveying chamber 121, thus avoiding damage or tearing of the shim surface.

[0039] In some embodiments, see Figure 4As shown, the bottom of the inlet 130 and the pressing fixture 100 have a first distance L1 along the vertical direction, and the bottom of the outlet 140 and the pressing fixture 100 have a second distance L2 along the vertical direction. The first distance L1 is greater than the second distance L2, so that the first conveying cavity 111 and the second conveying cavity 121 are inclined. Specifically, since the bottom film and the padding adhesive are bonded together, the bottom film will contact the bottom wall surface of the first conveying cavity 111, that is, the wall surface of the first conveying cavity 111 facing the second conveying cavity 121 along the vertical direction. Therefore, in this embodiment, the first distance L1 and the second distance L2 are measured with the bottom wall of the first conveying cavity 111 as a reference. By setting the first conveying cavity 111 and the second conveying cavity 121 at an angle, the base film and the padding adhesive can slide along the inner walls of the first conveying cavity 111 and the second conveying cavity 121 under the action of gravity after entering the first conveying cavity 111 and the second conveying cavity 121 respectively, thereby improving the conveying efficiency of the base film and the padding adhesive and promoting the screen manufacturing efficiency.

[0040] It should be noted that if the first conveying cavity 111 and the second conveying cavity 121 are inclined, and a pressing part 122 is to be provided on the second conveying cavity 121, then the slope of the pressing part 122 needs to be greater than the slope of the bottom wall of the first conveying cavity 111. That is, the inclination angle of the pressing part 122 is greater than the inclination angle of the first conveying cavity 111, so as to ensure that the bottom film and the padding adhesive can be subjected to the gradually increasing extrusion pressure of the pressing part 122 during the conveying process, thereby improving the pressing efficiency of the bottom film and the padding adhesive.

[0041] In some embodiments, see Figure 2 and Figure 3 As shown, the pressing fixture 100 includes a first clamp 110 and a second clamp 120. The second clamp 120 is positioned vertically above the first clamp 110, and the first clamp 110 and the second clamp 120 are detachably connected. Specifically, since the shim-raising adhesive is a gel-like substance with adhesive properties, when the shim-raising adhesive is conveyed between the first clamp 110 and the second clamp 120, some of the adhesive will adhere to the inner wall of the second clamp 120. Detachably connecting the first clamp 110 and the second clamp 120 can improve the assembly speed of the pressing fixture 100, thereby enabling quick disassembly and assembly of the first clamp 110 and the second clamp 120 to clean residual adhesive inside the second clamp 120, preventing adhesive from clogging the second conveying cavity 121 and affecting the use of the pressing fixture 100.

[0042] Furthermore, in some embodiments, see [reference] Figure 2 and Figure 3As shown, a first conveying cavity 111 is recessed along the vertical direction on the side of the first clamp 110 facing the second clamp 120, and a second conveying cavity 121 is recessed along the vertical direction on the side of the second clamp 120 facing the first clamp 110. Specifically, the first conveying cavity 111 and the second conveying cavity 121 are formed separately on the first clamp 110 and the second clamp 120, respectively. This makes the shape and structure of the first clamp 110 and the second clamp 120 more regular, thereby reducing stress concentration in the first clamp 110 and the second clamp 120 and improving the strength of the pressing fixture 100. At the same time, having the first conveying cavity 111 separately located on the first clamp 110 and the second conveying cavity 121 separately located on the second clamp 120 can also simplify the processing and manufacturing of the pressing fixture 100, thereby improving the manufacturing convenience of the pressing fixture 100.

[0043] Furthermore, in some embodiments, see [reference] Figure 2 As shown, the first clamp 110 has a mounting hole 112 formed downwards on the side facing the second clamp 120. The pressing fixture 100 also includes a fixing member 160 for connecting to the mounting hole 112. The fixing member 160 is connected to the side of the second clamp 120 facing downwards towards the first clamp 110. When the first clamp 110 and the second clamp 120 are connected to each other, the fixing member 160 is fixedly connected in the mounting hole 112. Specifically, the mounting hole 112 and the fixing member 160 are respectively located on both sides of the first conveying cavity 111 and the second conveying cavity 121, thereby preventing interference between the base film and the shim adhesive when they enter the interior of the pressing fixture 100 for conveying, which would affect the conveying of the base film and the shim adhesive. Furthermore, by setting the fastener 160 and the mounting hole 112, the assembly accuracy of the first clamp 110 and the second clamp 120 can be improved, and the corresponding positions of the first conveying cavity 111 and the second conveying cavity 121 can be deviated after the first clamp 110 and the second clamp 120 are connected and assembled, so that the padding adhesive cannot be accurately attached to the bottom film.

[0044] In some embodiments, see Figure 2 and Figure 5As shown, the fixing member 160 includes a fixing part 161 and an adjusting part 162 connected to each other. The fixing part 161 is disposed in the mounting hole 112, and the adjusting part 162 is connected to the second clamp 120. The fixing member 160 and the adjusting part 162 are movably connected, and the adjusting part 162 can move relative to the fixing member 160 in the vertical direction to change the vertical distance between the first clamp 110 and the second clamp 120. Specifically, the padding adhesive and the base film are combined to give the screen a light-shielding effect, preventing light leakage from the screen and affecting the display effect. The light-shielding height of the padding adhesive often depends on parameters such as the screen size. Therefore, the height of the second conveying cavity 121 needs to be changed when dealing with different screens. Through the cooperation of the fixing part 161 and the adjusting part 162, when different padding adhesives are needed, the adjusting part 162 can be moved relative to the fixing part 161 to change the distance between the first clamp 110 and the second clamp 120. This allows the height of the second conveying cavity 121 in the vertical direction to be changed to fit the padding adhesive, thereby expanding the application range of the pressing fixture, improving the adaptability of the pressing fixture, and promoting the production efficiency of the screen.

[0045] In this embodiment, the adjusting part 162 is rotatably connected to the fixed part 161. The adjusting part 162 rotates relative to the fixed part 161 via a threaded connection to adjust the vertical distance between the first clamp 110 and the second clamp 120. In another embodiment, the adjusting part 162 can also be slidably connected to the fixed part 161. A slide rail is provided at the connection between the adjusting part 162 and the fixed part 161, allowing the adjusting part 162 to slide up and down relative to the fixed part 161 along the slide rail, thereby changing the vertical distance between the first clamp 110 and the second clamp 120. When the adjusting part 162 slides to a designated position on the fixed part 161, a limiting structure such as a pin restricts the movement of the adjusting part 162, keeping the adjusting part 162 and the fixed part 161 connected and fixed.

[0046] A second aspect of this utility model provides a pressing mechanism, see reference. Figures 1 to 5 As shown, the pressing mechanism includes the pressing fixture 100 and the pressing roller described in any of the above embodiments. The pressing roller is located downstream of the pressing fixture 100 and corresponds to the discharge port 140 of the pressing fixture 100 in the front-back direction. The pressing roller is used to perform a second pressing on the bottom film and the padding adhesive output from the discharge port 140.

[0047] Specifically, along the conveying direction of the base film and the elevating adhesive, the pressure roller is positioned below the discharge port 140. The pressing fixture 100 is used to perform the first pressing of the base film and the elevating adhesive, so that the elevating adhesive can be bonded to the designated position on the base film, preventing changes in the position of the elevating adhesive and the base film. When the base film and the elevating adhesive are bonded together and output from the discharge port 140, the base film and the elevating adhesive pass through the pressure roller, which performs a second pressing of the pre-pressed base film and the elevating adhesive to further improve the bonding strength of the base film and the elevating adhesive, thereby completing the pressing operation.

[0048] The pressing mechanism of this utility model performs initial pressing of the base film and the padding adhesive through the discharge port 140 of the pressing fixture 100, so that the padding adhesive is precisely adhered to the base film. Then, the padding adhesive and the base film are pressed a second time by the pressure roller, thereby completing the pressing operation and improving the screen manufacturing efficiency. The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Furthermore, the embodiments of this utility model and the features in the embodiments can be combined with each other unless there is conflict.
